ROWING Application filed February 28, 1925.

T0 (ZZZ whom'tt may concern:

Be it known that I, GILMORE Boss, a citizen of the United States, residing at Sai'idpoint, in the county of Bonner and State of Idaho, have invented certain new and useful Improvements in Rowing lilachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to means for propelling small boats commonly known as row boats, and has for its principal object the provision of a propelling mechanism adapted to be mounted upon small boats of ordiiary construction by which the propulsion of the boats may be simplified and made more efficient.

A further object of the invention is the provision of a rowing machine that is so constructed with paddle blades that the blades enter the water in a substantially vertical position and retain this position until they emerge from the water so that the full force of the blades is exerted on the water throughout the length of the stroke.

The construction and advantages of the invention will be clearly described herein after and will be found illustrated in the accompanying drawings in which Figure 1 is a View in perspective of the improved rowing machine showing it in operation,

Figure 2 is a top plan view,

Figure 3 is a side view in elevation,

Figure 4; is a cross section on the plane in dicated by the line l4 of Figure 2, and

Figure 5, is a cross section on the plane indicated by the line 5-5 of Figure 2.

In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.

A boat is indicated at A on which the in1- proved rowing machine is installed. The rowing machine comprises two standards 1, one on each side of the boat a little forward of amidships, said standards beingpreferably formed as shown in the drawings of two bars secured to the sides of the boat and having their upper portions diverging, and a plate or block 2 secured between the two arms. 3 indicates brace rods connecting the forwardends of the plate or block 2v to the MACHINE.

inner and outer sides of the boat, and at indicates a similar brace rod extending rearwardly of the block 2.

Other-standards 5 similar in construction to the standards 1 are secured to the sides of the boat A near the stern and have plates 6 secured between the arms thereof and. are braced by means of bars 7.

Journaled on'plates 2 are crank shafts 8 that are actuated by cranks 9, and 10 indicates arms secured to the shafts 8 intermediate of their ends and having offset portions 11 on one of their ends and counterwcights 12 at their other ends.

13 indicates other arms journaled on plates 6 by means of an angular portion 14, and 15 indicates an offset portion at the free one of each arm 13.

On each side of the boat A is a bar 16 pivotally connected to the offset portions 11 and 15 of the arms 10 and 13 respectively, and secured to the bar 16 is a paddle blade 17 adjacent the forward end of the bar and strengthened by means of braces 18.

The arms 13 are longer than that part of each arm 10 between shafts 8 and offset portions 11 so that when the shaft 8 is rotated in operating the boat the rear end of the bar 16 will oscillate. It will be apparent that in operating the machine the paddle blades 17 will enter the water in a substantially vertical position and will maintaiir a vertical position during the propelling stroke and leave the water in substantially the same position, thus adding to the efiiciency of the propelling mechanism by e:'- erting the full force of the paddle blade on the water throughout the entire stroke.

It will also be understood that the device willbe operated by an operator facing the bow of the boat so that he is at all times facing the direction in which the boat is being propelled, and can readily steer the boat by proper manipulation of the propellers, each propelling mechanism being operated independently of the other.

What is claimed is 1. In a rowing machine, two arms pivotally mounted, one of said arms being shorter than the other, a bar pivotally connecting said arms, and a paddle blade secured to said bar.

2. In a rowing machine, a rotatable shaft, an arm secured to said shaft, another arm pivotally mounted and longer than the first mentioned arm, a bar connecting said arms, and a paddle blade secured to said bar.

In a rowing machine, a rotatable shaft, a counterweighted arm secured to said shaft, another arm pivotally mounted and longer than the first mentioned arm, a bar pivotally connecting said arms, and a paddle blade secured to said bar adjacent the first mentioned arm.

4. A rowing machine comprising in combination with a boat, standards mounted on said boat, a crank shaft journal'ed on one of said standards, an arm secured to said shaft another arm, longer than the first 'mentloned arm, pivotally mounted on. the other standard, a bar pivotally connecting said arms, and a paddle blade secured to said bar adjacent the first mentioned arm.

5. A rowing machine comprising in combination with a boat, standards mounted on said boat, a crank shaft journaled on one of said standards, an arm secured to said shaft intermediate of its ends, another arm longer than the first mentioned arm, pivotally mounted on the other standard, a bar pivotally connecting said arms, a paddle blade secured to said bar adjacent the first mentioned arm, and a counterweight on the free end of the first mentioned arm.

In testimony whereof I a'ffix my signature.

GILMORE BUSS.
